You can set up iTunes so that your iPhone and iPad sync via Wi-Fi. Then, so long as you're on the same network, your tunes, movies, TV shows, and tones will all sync up, so you don't have to waste time plugging your stuff in and missing out on a text, tweet, Farmville request, or snap.

Restart everything

If iTunes has been open on your computer for quite some time, it might just need a kick in the ass to get going. Quit the program and re-launch it. You should also restart your iPhone or iPad by holding down the power (sleep/wake) button until the power off slider appears and sliding to power off. Wait for your device to fully power off and then turn it on again.

Forget and rejoin your Wi-Fi network

Despite current Wi-Fi technology being better than ever, signals still get crossed sometimes and things go kablooey. Try forgetting and rejoining your Wi-Fi network on your iPhone or iPad.

Launch Settings from the Home screen of your iPhone or iPad.

Tap Wi-Fi.

Tap the network you're connected to.

Tap Forget This Network.

Tap Forget.

Tap Wi-Fi on the top left of your screen.

Tap the network to join it again.

Enter the password if there is one (there should be!).

Tap Join.

You'll now be reconnected to your Wi-Fi network. You may also have to forget and rejoin your network on your computer. Here's how to do it on Mac:

On your computer, click the Wi-Fi icon on the top right of your screen. It looks like waves.

Click Open Network Preferences at the bottom of the list.

Click Advanced.

Click the name of the network you're trying to forget.

Click the minus button just below the networks.

Click OK.

Click the Wi-Fi icon on the top of your screen again (should be grayed out now).

Reset the network settings on your iPhone or iPad

Again, sometimes things just need a kick in the ass to get going, and while data from iTunes may be ready to sync, your iPhone or iPad may not be letting it through for one reason or another. Here's how to reset your network settings.

Note: Your network settings will be reset to factory defaults, so you'll have to re-enter all of your Wi-Fi passwords for any network you may use.
